How to Choose a Camera Battery
Start from the code on your original battery
The most reliable starting point is the code printed on the battery that came with the camera. Replacement batteries are organised by that code and by camera brand, and two batteries that look alike can differ in fitment. If the code on your item does not match the fitment named on a page here, ask before payment so the match can be confirmed.
Capacity and voltage are a pair, not a single number
Capacity tells you how much charge a pack holds; voltage tells you the electrical level it delivers. The one fully specified replacement battery on this site, the Action6 battery, has its own detail page with a specification table covering capacity, voltage, charging cycles and size. That table is the only battery specification table on this site; other battery pages are family or fitment pages and do not carry specification tables, and they do not repeat the Action6 figures.
For any other battery, confirm the voltage and capacity that your camera requires, and confirm them against the supplier's answer before payment rather than assuming a look-alike pack will match.
Charger match matters as much as battery match
A replacement battery is only useful with a charger that fits its code and input. The DMW-BLK22 LCD dual charger on this site has its own detail page with a specification table covering slots, inputs, per-slot output and protections. Use that pattern as a checklist: slots, input, per-slot output, and protections, and read the figures on the detail page rather than on this guide.
Before ordering, check the code printed on your original battery or charger and the camera model it came with. If the code on your item does not match the fitment named on this page, ask through the inquiry form before payment so the match can be confirmed. Certificates available upon request.
Confirm the battery or charger code printed on your original item, the voltage and capacity you need, and the certification scope and warranty terms that apply to your order. Confirm MOQ, lead time and pricing for your order through the inquiry form before payment. Certificates available upon request.
Wholesale inquiry — Send the camera model, the accessory type and the quantity range you are planning through the contact form, and the supplier can confirm fitment and terms for your order.
